Preheat your oven to 400°F (200°C).
Prepare the zucchini by grating it; then, place it in a clean kitchen towel to remove excess moisture.
In a mixing bowl, combine the grated zucchini, mozzarella cheese, Parmesan cheese, egg, garlic powder, Italian seasoning, salt, and pepper.
Spread the mixture evenly onto a greased baking sheet in a rectangle shape.
Bake in the preheated oven for 20-25 minutes or until the edges are golden brown.
Remove from the oven and let cool slightly; then cut into sticks.
Serve warm with marinara sauce or your favorite dipping sauce.
